Mehouel et al. 2019 - Risk assessment of mercury and methyl mercury intake via sardine and swordfish consumption in Algeria
This study measured total mercury and methylmercury in sardine and swordfish from three Algerian coastal areas and estimated dietary exposure for adult consumers.
Key numbers
Source units are mg/kg wet weight unless otherwise stated.
- Sample size: sardine n=43 and swordfish n=44, total n=87.
- Sardine: total Hg 0.04 +/- 0.03; MeHg 0.04 +/- 0.028.
- Swordfish: total Hg 0.61 +/- 0.47; MeHg 0.57 +/- 0.45.
- Highest regional swordfish values reported in text: North Centre/Algiers total Hg 0.77 +/- 0.41 and MeHg 0.64 +/- 0.38.
- EDI for swordfish: total Hg 0.098 ug/kg bw/day; MeHg 0.092 ug/kg bw/day.
- EWI for swordfish: total Hg 0.7 ug/kg bw/week; MeHg 0.64 ug/kg bw/week.
Methods
Total Hg was determined by direct mercury analyzer. MeHg was extracted and quantified as Hg; the paper reports LOD/LOQ of 0.010/0.020 mg/kg for MeHg.
Implications
This source supports Algerian swordfish and sardine mercury occurrence with explicit total-Hg and MeHg speciation. The authors compare values against 0.5 mg/kg for sardine and 1 mg/kg for swordfish.

Verification notes
- Source identity checked against DOI 10.12681/jhvms.21792 and the downloaded PDF.
- Total mercury and methylmercury values are separate species and should remain separate during routing.
